随着网络化播出成为电视台主要的播出方式,以磁盘阵列为播出节目存储介质、视频服务器为播出设备的播出系统已成为主流的电视播出方式,传统录像机放像逐渐变为应急备播或跟播。由于前期节目摄制和节目交换采用磁带、蓝光盘和P2卡等移动记录存储介质,对内容上载仍是数字化网络化制作和播出系统必不可少的环节。本文结合电视播出系统安全控制及质量控制,对节目上载与播出安全、播出质量的关系进行了一些技术总结,期待与同行进行探讨。
With the network broadcast as the main broadcast television stations to disk array for the broadcast program storage media, video server for the broadcast equipment broadcast system has become the mainstream television broadcast, the traditional video playback gradually become Emergency backup or broadcast. Due to the pre-program production and program exchange using removable storage media such as tapes, Blu-ray discs and P2 cards, content uploading is still an integral part of digital networked production and playout systems. In this paper, the TV broadcast system security control and quality control, the program upload and broadcast safety, broadcast quality of the relationship between some technical summary, looking forward to discuss with their peers.
